Sirenevyy boulevard is the central public space of the science town of Troitsk. The announced competition for urban improvement aims to find a starting point for the long-term development of the entire city as a whole. The project shows the unique features of this place, preserve the atmosphere of the original project of the boulevard and create a favorable modern environment for a comfortable life for citizens and the development of the tourist attraction of the city. During the process of work, we formed three principles of the project: structure, locality, relevance. The structure of the project is its planning frame of the town with the restored axis of the boulevard. It also embodies the structure and logic of scientific thinking and supports the image of a science city. Locality is the result of a search for identity in local materials and forms - the use of brickwork as the main material, as well as arches, column articulation and other characteristic forms. The project provides careful attitude to the existing environment and landscape including forest restoration. The relevance of the project is created by a meta-analysis of the wishes of residents.
